Computer Architecture Quiz

Which of the written below is NOT increase power consumption?

• Increasing multithreading

• Increasing performance

• Increasing multiple cores

What is a hash table?

• Popular data structure for organizing a large collection of data items so that one can quickly answer questions

• Popular data structure for updating large collections, so that one can hardly answer questions

• Popular tables for organizing a large collection of data structure

• Popular data structure for deletingsmall collections of data items so that one can hardly answer questions

How many fields contains the entry in the ROB:

• 4

• 5

• 6

• 3

Which of these is NOT characteristics of recent highperformance microprocessors?

• Color

• Power

• Functional unit capability

• Clock rate

For what the reorder buffer is used :

• To pass results among instructions that may be speculated.

• To pass parameters through instructions that may be speculated

• To get additional registers in the same way as the reservation stations

• To control registers

Which of the following descriptions corresponds to dynamic power?

• Proportional to the product of the number of switching transistors and the switching rate

• Grows proportionally to the transistor count (whether or not the transistors are switching)

• Certainly a design concern

• None of the above

(Performance for entire task using the enhancement when possible) / (Performance for entire task without using the enhancement) is equals to:

• Speedup

• Efficiency

• Probability

• Ration

If we want to sustain four instructions per clock

• We must fetch more, issue more, and initiate execution on more than four instructions

• We must fetch less, issue more, and initiate execution on more than two instructions

• We must fetch more, issue less, and initiate execution on more than three instructions

• We must fetch more, issue more, and initiate execution on less than five instructions

If speculation were perfect, it could save power, since it would reduce the execution time and save , while adding some additional overhead to implement

• Static power

• Dynamic power

• Processing rate

• Processor state

How this process called: "Operations execute as soon as their operands are available"

• data flow execution

• instruction execution

• data control execution

• instruction field execution
